The house was in "really good nick" in 2015, Goodier said, but has developed leaks and cracks since. The burglar who took some of the Goodiers' possessions has been caught, but it's unlikely he can make reparation.
Nicola and Mark Goodier are stressed by the long dispute and their loss of capital, and their health has suffered.
They have had one meeting to attempt mediation, and over nearly three years EQC has spent many thousands of dollars on engineers and geotechnical reports on their property.
Those costs must be easily more than the payout they need, Louis Goodier said.
"It's not in anyone's interest to take this to court. Financially it would make more sense to settle and let it go away."
No court date has been set so far.
